Answer / anbu
May be coal consumption is high. And the major issue is that the temperature of flue gas may reduced to below the acidic dew point then the tube erosion will occur in economiser coils and ESP also will disturb like lesser efficiency due to low charging performance.
Acidic dew point means that, H2So4 phase change occur from gaseous state to liquid state.

Answer / selvalagan
Air pre heater air outlet temperature will be high and Economiser outlet water temperature is low.
So boiler efficiency is become low.

Answer / dk
satuated temperature very low temperature and air heater outlrt air & pa air also hot air above 200c and fuel consumption not high as possible only reason for economiser o/l temperature only decreased
